Chargers sign CB Crezdon Butler

The Chargers have signed free-agent cornerback Crezdon Butler and released defensive end Drake Nevis, the club announced Tuesday.

The Bills released Butler, 6-foot and 183 pounds, at the end of training camp last month.

The Chargers are the fifth team to employ Butler, 26. In four seasons, he has played in 11 games without a start.

His head coach with the Cardinals in 2011 and 2012 was Chargers offensive coordinator Ken Whisenhunt.

The Steelers used a fifth-round draft pick on Clemson's Butler in 2010. Along with the Cardinals and Bills, the Redskins employed him last year. He is the fifth defensive player signed by the Chargers since their final preseason game ended.
